论文摘要
全息暗能量（HDE）描述了宇宙IR区域中的真空能量，其总能量饱和避免崩溃成黑洞的极限。 HDE预测，国家的黑暗能源方程式从大于$ -1 $的政权到$ -1 $ $ -1 $，在早期阶段加速了宇宙较慢，并且在后期更快。我们将HDE作为新的{\ it物理}解决方案，以解决宇宙微波背景（CMB）和局部测量之间的哈勃常数差异。随着Planck CMB和Galaxy Baryon声学振荡（BAO）数据，我们将Hubble常数的HDE预测符合$ H_0^{} {} {} {} \！= \，71.54 \ pm1.78 \ pm1.78 \， $ H_0^{} $测量LMC CepheID标准（R19）$1.4σ$级别。结合Planck+Bao+R19，我们发现HDE参数$ C = 0.51 \ PM0.02 $和$ H_0^{} {} \！ = 73.12 \ pm 1.14 \，\ Mathrm {km \，s^{ - 1} mpc^{ - 1}} $，在所有红移中都符合宇宙学数据。未来的CMB和大规模结构调查将进一步测试全息图。
Holographic dark energy (HDE) describes the vacuum energy in a cosmic IR region whose total energy saturates the limit of avoiding the collapse into a black hole. HDE predicts that the dark energy equation of the state transiting from greater than the $-1$ regime to less than $-1$, accelerating the Universe slower at the early stage and faster at the late stage. We propose the HDE as a new {\it physical} resolution to the Hubble constant discrepancy between the cosmic microwave background (CMB) and local measurements. With Planck CMB and galaxy baryon acoustic oscillation (BAO) data, we fit the HDE prediction of the Hubble constant as $H_0^{}\!=\, 71.54\pm1.78\,\mathrm{km\,s^{-1} Mpc^{-1}}$, consistent with local $H_0^{}$ measurements by LMC Cepheid Standards (R19) at $1.4σ$ level. Combining Planck+BAO+R19, we find the HDE parameter $c=0.51\pm0.02$ and $H_0^{}\! = 73.12\pm 1.14\,\mathrm{km \,s^{-1} Mpc^{-1}}$, which fits cosmological data at all redshifts. Future CMB and large-scale structure surveys will further test the holographic scenario.
